GENERAL DESCRIPTION
The ADV7782 is a receiver that is compatible with an APIX® or
APIX2® serial data stream. The ADV7782 performs limited
processing (color space conversion and interpolation 4:2:2 to 4:4:4),
and forwards the data via MIPI® camera serial interface (CSI).
Data from the LVDS input (OpenLDI) can also be routed through
the same processing blocks. It supports a point-to-point connection
topology, and supports HDCP repeater implementations with a
key selection vector (KSV) list memory of 25 entries.
There are three primary video sources: LVDS OpenLDI, APIX
Channel 0, and APIX Channel 1. These three primary video
streams are input to a video switch matrix. Any two of the three
streams can be selected and output from the switch matrix.
Of the two video channels output from the video switch matrix,
one output channel is unprocessed, and the other output channel
passes through a combination of an interpolation block (4:2:2 to
4:4:4) and a color space converter.
